Anthozoans are exclusively marine, and include sea anemones, stony corals, soft corals, sea pens, sea fans and sea pansies. Anthozoa is the largest taxon of cnidarians; over six thousand solitary and colonial species have been described. They range in size from small individuals less than half a centimetre across to large colonies a metre or ...
Corals reproduce both sexually and asexually. An individual polyp uses both reproductive modes within its lifetime. Corals reproduce sexually by either internal or external fertilization. The reproductive cells are found on the mesenteries, membranes that radiate inward from the layer of tissue that lines the stomach cavity. Some mature adult ...
Primnoa pacifica or red tree coral is a species of soft coral in the family Primnoidae. It is a deep water coral found in the North Pacific Ocean, and plays an integral role in supporting benthic ecosystems. Red tree corals grow axially and radially, producing structures of calcite and gorgonian skeletons that form dense thickets.
Many soft corals are easily collected in the wild for the reef aquarium hobby, as small cuttings are less prone to infection or damage during shipping than stony corals. Nevertheless, home-grown specimens tend to be more adaptable to aquarium life and help conserve wild reefs.
Callogorgia is a genus of soft corals in the family Primnoidae. Callogorgia exhibit a fan shaped body structure that often serves as a habitat for other organisms. [2] [3] Callogorgia are a relatively recently researched genus, with most studies occurring in the last 40 years. [3]
Public engagement is critical at this stage to address issues and raise awareness of activities that promote the spread of soft corals through fishing, boating and marine aquarium dumping. For ...
A staggering 77% of the world’s coral reef areas — from the Atlantic to the Pacific to the Indian oceans — have so far been subjected to bleaching-level heat stress, according to satellite ...
Like all shallow-dwelling corals, P. cylindrica gametes are buoyant, and float to the surface of the water to merge. [9] The brooding coral internally fertilizes its eggs, which contain the algae zooxanthellae evenly distributed within, allowing the new coral larvae to be born having already established a relationship with their symbiotic algal ...
